The Alternative Energy Technologies (AET) AE Series Drainback has been designed to be a complete solar appliance that incorporates ease of installation and maximum efficiency for years of trouble-free service. The Drainback system uses the sun’s energy to heat your water, reducing your electricity consumption. The Drainback will pay for itself many times over the life of the system. All installations require a connection to your home water system.

Since only thermally efficient pure water is used, maximum safety and performance is assured. The Drainback system is ideally suited to cold regions with many freezing days each year or areas with aggressive water conditions. Freeze protection is provided by draining the collector loop liquid back into the drainback reservoir when the system is not operating. The simplicity of the drainback method provides reliable operation that makes this system an asset to any home located in the colder climes.

AET Drainback System consists of:

Collector(s)

Drainback reservoir

Storage tank

Heat exchanger

Circulation pump(s)

System controller

Pre-engineered system

AET Indirect (Closed Loop) Drainback Models:

• DB Drainback - The system collects heat by circulating water between the reservoir, collectors and a heat exchanger wrapped around the base of the storage tank.

• DX Drainback - Unique drainback reservoir with built-in heat exchanger. This allows the use of a lightweight glass-lined storage tank. This system collects heat by circulating water between the reservoir and collectors and simultaneously, between the storage tank and the heat exchanger inside the reservoir. Includes 2 pumps.

• DBS Drainback - The system collects heat by circulating water between the reservoir, collectors and a heat exchanger wrapped around the base of the storage tank. It has a single wall heat exchanger and one circulating pump/control combo.

Only a qualified person or someone thoroughly familiar with standard plumbing and electrical practices should do the installation. If you have questions on the proper methods to make these connections, consult a qualified plumber or solar contractor for prescribed methods in your area. In most cases your installing solar contractor is familiar with the codes and their application. The codes are intended to protect the health, safety, and welfare of the public.
